Be it known that 1, RO ERT HnNN E-i MAN a citizen of the United States, residing at Wausau, in the county of'Marathon, State of Wisconsin, have invented certain new and useful Improvements in Railway-Switches;

and I do hereby declare the "following to be a fulh clear,fand exact description of the,

invention, such aswill enable others skilled in the art to which it. appertains 'to' make the type which is controlled atthe will of the engineer cperatingfa train;

The principal object of the invention 15 to provide animproved railroad switch of this description which will be sure in operation', cannot get out of order accidentally, and cannot be tampered with by unauthoriz'ed persons. 1 p I Anothenobject of the invention is to improve the track devices used in connection with said switches.

A third object of the invention is to pro vide an improved form of controlling device arranged to becarried 'onthe'locomotive and used in connection with the improved track devices.

The pit wherein this crank shaft works is provided with a cover 35 which extends transversely across thetrack and supported beneath tlllS; cover 35 I are certain rollers 36 whereon work a segmental cylindrical plate 37 having a frustoconical opening 38 in its center -wherethrough passes the member 33. It is to be understood that the plate 35 also has an openingin its center so that the member 33 can be moved backward and forward thus carrying with it the closure plate 37 so that gravel and sand is prevented from dropping into the pit while'at the same time said member can have free movement.

In order to protect the working parts from robbers and the l ke certain I beams are employed whereon are secured doors as shown, these I beamsbeing indicated at 40 and the doors shown at 41. These doors are hinged to the I beams 40 and overlap at their meeting edges, and are adapted to be locked or secured together in any suitable manner, such as by the bolts 42, and these bolts may be of any preferable or special I form, capable of being manipulated only by means of special keys or wrenches. v 7

Turning now to those parts of the device which are supported on the engine and which are shown in Figs.'5 to 8 inclusive. Attached to the engine isa suitable frame work which is indicated in general at 45. Mounted on this frame work is a steam cylinder 46 provided with the usual piston and the rod of which is shown at 48, the latter being supported in an outboard bearing car ried bycertain brackets of the frame as indicated at 49. This steam cylinder is provided with certain inlet pipes 50 at each end thereof and on the under side of the cylinder there are provided the outlet pipes 51. These inlet pipes are controlled by suitable valves 52 and levers 53, these le vers being connected by the link 54. The arrangement is such that when one of these valve is opened the other is closed. In like manner the valves to pipes 51 are provided with a connecting link 55 so arranged that when one valve is open the other will be closed. These links 54 and 55 are connected by links 56 to a lever 57 pivoted to the frame and to this lever is in turn connected a link 58 which has its remaining end connected to a latch lever 59 provided with the usual latch working over a quadrant 60. The arrangement of the links 56 and lever 57 is such that when taken in connection with the links said lever 57 to open and close said ports or valves.

Mounted on the frame 45 is a bearing 61 wherein is journaled a rock shaft 62 carrying on one end a rock arm 63 which passes upward through a collar 64, said collar being rotatably mounted on certain pivots and located in a slot 65 formed in the piston rod 48, the pivots being indicated as set screws 66. The other end of this rock shaft 62 is provided with a tubular rock arm 67'wherein is mounted a plunger 68, said rock arm having a head 69 in its lower end wherethrough Furthermore depending from the frame 45 are certain frame members or supports 7 4 whereto are pivoted arcuate arms 75, the free ends of which being normally drawn toward each other by means of a spring 76. These arcuate arms furthermore carry certain gripper jaws 77 which are arranged to swing away from each other when the arms are forced apart and to swing toward each other when the arms are drawn together, On the member 56 is a pair of spaced ooni cal wedges 78 which are arranged to selectively engage theaperture between respective'pair-s of arms 75 so that by the movement of the rack 56 the gripper jaws 77 will be moved toward or away from each other.

It'will be obvious that an ordinary target stand 79 may be employed in connection with this invention and this target stand may be connected to the switch operating bar by meansofra link 80 sothat as the switch is moved the proper position of the target will be indicated. v

The operation of the device is as follows:

Assuming that a train is approaching the switch from the right hand side of Figs. 1, and 1*, it is apparent that it will be necessary to operate the trip member 34to the right of said figures. To perform this op-, eration the engineer operatesthe lever 59 to move the piston in the cylinder 46 to the left in 5, until the member 72 moves to a vertical position inwhich position its lower end Wlll engage the trip 34. When the trip. 34 is engaged by the member 72, it will be 'seen'that the operating rod 32 will be moved to throw its respective cam member into engagement with the cutout portion 19 of the cross bar 15 to operate the switch thus permitting the train to enter the main line from the siding 11. When the member 34 has been operated and the switch moved, upon the engagement of the member 72 with the member 34, said member 34 will return to its initial position under the influence of the springs 30, and this movement will take place Without in any manner aifecting the position of the switch points by reason of the operating rod 32 being provided with the elongated eye 32.

After this operation has taken lace it will be seen that the switch will be left open to a train approaching from the left, and if it is desired to continue on the main line, the operating member 34 to the left of Figs. 1 and 1 is operated in the manner heretofore described. After the switch has been operated, the engineer throws the lever 59 to moVe the piston 65. in the cylinder 24 and this action moves the member 72 to either of its supporting elements 7 7 as desired by the engineer.

There has thus been provided a simple and efficient device of the kind described and of the character specified.

It will be obvious that many minor changes may be made in the form and construction of this invention without departing from the material principles thereof. It is not therefore desired to confine the invention to the exact form herein shown and described, but it is wished to include all such as come properly within the scope claimed.

Having thus described the invention, what is claimed as new, is

1. In a device of the kind described, the combination with a switch operating track Gopies of this patent may be obtained for five cents each, by addressing the supported mechanism, of means carried by locomotives for actuating said mechanism, said means comprising a cylinder, inlet and outlet valves at each end of the cylinder, a piston movable in said cylinder, a piston rod projecting from said cylinder, a collar pivotally carried by said rod to rock in a vertical plane, a rock shaft mounted beneath said rod, an arm fixed on said rock shaft and projecting through said collar, and a track device engaging arm fixed on said rock shaft and resiliently extensible, and means under the control of an operative for opening and closing said valves selectively.

2. In a device of the kind described, the combination with a switch operating track supported mechanism, of means carriedby locomotives for actuating said mechanism, said means comprising a cylinder, inlet and outlet valves at each end ofthe cylinder, a

piston movable in said cylinder, a piston rod projecting from said cylinder, a collar pivotally carried by said rod to rock in a vertical plane, a rock shaft mounted beneath said rod, an arm fixed on said rock shaft and projecting through said collar, a track device engaging arm fixed on said rock shaft and resiliently extensible, means under the control of an operative for opening and closing said valves selectively, and a safety device arranged to engage the last mentioned arm when in inoperative position.

In testimony whereof, I afiix my signature, in the presence of two witnesses.
